Integrated solar still with an underground heat exchanger for clean water production

Applications of Heat Exchanger in Solar Desalination: Current Issues and Future Challenges

“…Hammadi [59] found that a ground heat exchanger coupled with a solar still benefited soil temperature, as shown in Figure 6. They dipped an HE pipe with a 0.2 m diameter and 70 m length 1 m into the soil.…”

Adsorption-based atmospheric water harvesting

“…The second solution is to reduce the condenser temperature. Besides the conventional compressive systems, 57 solar-powered Peltier modules, 70 keeping night temperature using phase change materials (PCMs), 47 radiative cooling, 89 and underground temperature 90,91 are low-cost and low-energy consumption solutions that can help reduce condenser temperature. The type of cold source, like the energy source, depends on environmental conditions.…”

Recent Developments of Solar Stills and Humidification De-humidification Desalination Systems: A Review

“…Kaczmarczyk et al [50] analysed a Novel treatment of geothermal wastewater with low-enthalpy geothermal energy. Hammadi [51] proposed modelling solar desalination augmented with geothermal energy serving as a condenser, as shown in Fig. 1.…”
